Image code transform system for separating coded sequences of small screen moving image signals of large screen from coded sequence corresponding to data compression of large screen moving image signal

摘要

An image code transform system for arranging and composing a plurality of small screens of moving images to a large screen image, compressing and encoding the large screen image to generate a large screen compressed/coded data sequence, and extracting small screen compressed/coded data sequences of the plurality of small screens of moving images from the large screen compressed/coded data sequence. The system includes a multiplexer for re-arranging frames of the plurality of small screen moving images at an identical time to generate a composite frame and generating a large screen moving image signal of the composite frame; a compressor/encoder for compressing and encoding the large screen moving image signal on a block basis to generate a large screen compressed/coded data sequence signal and for outputting the large screen compressed/coded data sequence signal, the block being obtained by dividing the large screen moving image signal; and a separator/converter for separating and converting a plurality of small screen compressed signals corresponding to the plurality of small screens directly from the large screen compressed/coded data sequence signal.
